Many people say that one must not drink Tea in the evening, as it can affect sleep. While tea does have a stimulating effect, it can also help calm the mind. Scientifically adjusting your method of Drinking Tea will not only prevent insomnia but also ensure the quality of your sleep.

The reason tea has a stimulating effect is mainly due to its Caffeine content. Generally, caffeine is the first component to dissolve in water after about two minutes of brewing, making the tea very stimulating at this point. After two minutes, polyphenols start to leach out from the tea, which to some extent counteracts the stimulating effects of caffeine, reducing its impact on the nervous system. Therefore, it's fine to drink tea in the evening; you just need to discard the first brew after two minutes and brew it again.

Additionally, it's recommended to drink black tea instead of Green Tea in the evening. Green tea, being unfermented, contains a higher amount of caffeine and is very stimulating, which is not conducive to sleep. Black tea is different. As a fully fermented tea, it contains fewer polyphenols and, after undergoing maturation, becomes less stimulating, with a very mild nature. If you have a weak stomach, you can add a little milk to your black tea, which can help warm and soothe your stomach.

Of course, for some special individuals, it's best not to drink tea in the evening. This includes those who are easily agitated, have very poor digestive function, or have consistently bad sleep. It's advised not to drink tea. When drinking tea in the evening, avoid overly strong brews and opt for lighter ones instead.
